Abstract : This Final Report describes the research progress in the Cross-Disciplinary Materials Program at the University of Pittsburgh during the period February 1, 1995 through April 30, 1997. Research has been Undertaken in three technical areas; High Performance Materials, Optoelectronics, and Catalysis. The projects in High Performance Materials include studies on the oxidation of superalloys, coatings, and other intermetallics, the thermoprocessing of near gamma-TiAl, the wear of diamond films and monitoring diamond growth with UV Raman Spectroscopy, the modeling of blending and the modeling of adhesion of polymers, and the attempt to remove sulfur from liquid metals. Optoelectronics projects are concerned with multi-quantum well devices, polymerized crystalline colloidal arrays to be developed for laser eye protection, synthesis of non-linear metallo-organic compounds, determination of carrier concentration in n-type H and 6HSiC, and an electron beam method for growing epitaxial SiC. The Catalysis projects are involved with a new automotive catalyst for decomposition of NOx, studies of the dechlorination of chlorofluorocarbons, the synthesis of new transition metal compounds for catalysts, and the results of using hydroxyapatite and fluorohydroxyapatite for decomposition of nerve gas.
